HENRY H. UNRUH, OF GREAT BEND, KANSAS.

POST-HOLE AUGER.

To all whom it may concern:

Be it known that I, HENRY H. UNBUl-I, a citizen of the United States, residing at Great Bend, in the county of Barton, State of Kansas, have invented certain new and useful Improvements in Post-Hole Angers; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in earth augers, and particularly to angers for boring post holes.

One object of the invention is to provide an etficient means for weighting down the auger when boring in hard ground.

Another object is to combine with such weighting means, a means on which. the operators may stand to add to the weight while turning the staff of the auger.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: Figure 1 is a front elevation of my attachment applied to the staff of the auger, Fig. 2 is a side elevation of the same, Fig. 3 is a top plan view of the device, the staff being shown in section, Fig. 41 is a section on the line 41 of Fig. 1.

Referring particularly to the accompanying drawing 10 represents the threaded staff of the earth auger, one end of said staff being provided with a cross handle 11., while the other end is formed with a threaded extension 12 to which a suitable auger bit may be attached. Mounted to move longitudinally on the staif is an internally threaded block 13, this block having formed in two of its opposite sides, grooves 14. A member 15 formed of metal or other suitable material is disposed against one side of the block and is formed with a pair of fingers 1G for detachable engagement in the grooves 14 of the block. This member carries centrally a clamping bolt 17 on which are mounted the slotted ends 18 of the brackets 19, suitable nuts 20 being screwed on the bolt to hold the brackets securely on the said member. On the outer end of each of the brackets is a foot rest or platform 21, on which two operators may stand while they turn the Specification of Letters Patent.

staff by means of the handle 11. On the lower edge of the slotted portion of one of the brackets is a stop flange 22 for engagement with the adjacent edge of the other slotted portion. The other slotted portion 18 provided with a flange 23 on its upper edge for engagement with the adjacent edge of the first portion. Thus the brackets are pivotally mounted on the member 15, so that they may be rocked in a seesaw fashion, while by means of the bolt 17 and the slots the foot rests may be adjusted toward and away from each other. It will, of course, be understood that the foot rest attachment may be quickly removed when it is not desired to use the same.

From the foregoing it will readily be seen that when the operators stand on the foot rests and turn the handle their combined weight will assist in driving the auger into the ground, especially where the ground is very hard.

That is claimed is:

1. The combination with the threaded staff of an earth anger, of an operators stand for weighting down the auger comprising, athreaded block movable longitudinally on the staff, and foot rests detachably mounted on the block.

2. The combination with the threaded staff of an earth anger, of an operators stand for weighting down the auger comprising, a threaded block movable longitudinally on the staff, foot rests detachably mounted on the block, and means for adjusting the foot rests toward and away from each other.

3. The combination with the threaded staff of an earth anger, of an internally threaded and externally grooved block movably mounted on the staff, a supporting member having fingers engaging in the grooves of the block, and a plurality of foot rests pivotally mounted on the supporting member and adjustable toward and away from each other.

In testimony whereof, I affix my signature, in the presence of two witnesses.
